Abstract
The present application discloses an interference coordination method and an apparatus, which are applied to the communications field and can determine, among inter-RAT networks that share a frequency spectrum, a physical resource for interference coordination. The method includes: acquiring, by a second base station, time-frequency position information corresponding to cell key information of a first base station, where the time-frequency position information is used for determining a time-frequency position that is corresponding to the cell key information of the first base station and that is on a shared time-frequency resource, and the cell key information includes at least one of a cell-specific reference signal (CRS), a channel state indication-reference signal (CSI-RS), a physical broadcast channel (PBCH), and a synchronization signal. The method also includes performing, by the second base station, interference coordination on the first base station.
